- •
Vertically aligned, uniform core–shell W18O49/CuO nanorod arrays is reported.
- •
The alignement of heteroarrays can be tuned easily by shell layer deposition.
- •
Possible mechanism of shell-induced alignment is suggested.
- •
W18O49/CuO sensor response NO2 as low as 100 ppb at near room temperature.
- •
Mechanism of improved NO2 sensing characteristics is discussed.
